useful Improvements in Folding Boxes, of

which the following is a specification.

This invention relates to improvements in folding boxes especiallyadapted for use as cracker boxes and also adapted for other .nses and itconsists in the construction, com-- binatidfri and arrangement ofdevices hereinafter, described and claimed.

In the accompanying drawings, Fi ure 1 is a perspective view of myimproved folding box, showing the same set up. Fig. 2 is a verticaltransverse sectional view of the same, taken on the plane indicated bythe line a-a of Fig. 1. Fig. 3 is a detail horizontal sectional view ofthe same, showing a portion of oneof the end walls, a portion of one ofthe side walls and alsoshowing the devices which form a corner jointbetween said walls. Fig. 4.- isa vertical detail sectional view, showinga portion of one of the sidewalls, a portion of one of the end wallscorner joint between said walls.

and also showing the devices which form the vertical longitudinalsectionalview of my improved folding box, showing the" same set up,taken on the plane indicated by the line 79-?) of Fig. 2. Fig. 6 is asimllar view, showing the same folded; Fig. 7 is a vertical transversesectional view of the same,

showing the box folded. Fig. 8 is a detail horizontal sectional view ofa portion of one of the front walls, showing the means for detachablyconnecting the top thereof. Fig. 9 is a detail section on an enlargedscale showing a portion of the wall 3, one of the recesses in its upperedge, one of the loops which depend from the top and one of the pinswhich lock such loop in such recess.

My improved folding box comprises the bottom 1, the end walls 2, theside walls 34 and the top 5. Metallic straps 6 are secured transverselyon the bottom near the ends thereof. Similar straps 7 are secured to theinner sides of the end walls 2 at their lower edges and the said straps6 and 7 are provided with co-acting hinge members whereby said end wallsare hinged to the bottom and are adapted to be folded inwardly thereon,as shown in Figs. 6 and 7. Metallic angle straps 8-'9 have lowerhorizontal wehs secured longitndinalllon the Fig. 5 is a bottom near thesides thereof. The vertical webs of the said angle strapsare of unequalheight, that of the strap 9 being higher. The side wall 3 is hinged tothe vertical web of the angle strap J by means of a metallic strap 10which is secured to the inner side of said side wall at a distance fromthe lower edge thereof corresponding to the height of the vertical wallof such angle 'strap' 9. The side wall 4 is similarly hinged to thevertical web of the angle strap 8 by a metallic strap 11 which issecured to its inner sideat a distance from its lower edge correspondingto the height of the vertical web of such angle strap 8. Ilence the saidwalls are adapted to be folded over the bottom and over the end walls 2,as shown in Fig. 7 to elfect compact disposition of the walls of the boxand enable the same to be folded into small compass.

' On the upper edge of the wall 3 is secured the longitudinally disposedguide strap 12 provided near its ends with oil'set portions 13. The top5 is provided on its under side near its ends with transversely disposedconnecting straps 14: which extend through said ofi set portions 13 ofthe strap 12 between the latter and the upper edge ofthe wall 3 and havetheir ends "connected to the side edges of the top, as shown in Figs. 2and 7. Each of the connecting straps 14 is provided at one end with adown turned, doubled, substantially Ushaped portion, forming aloop 15.The side wall 4- is provided in its upper edge with recesses 16 toreceive such loops. Straps 17 of metal are secured on the outer side ofthe wall 4 at the upper edge and near the ends thereof cover the outersides of such recesses 16 and have tongues 18 which bear against theinner sides of such recesses and are doubled over the edges of theintegral portions between said rec'csses and the inner surface of suchwall. The

loops 1!) of the connecting straps 1-1 are adapted to be placed in therecesses 16 and pins '19 may. be inserted in openings in such wall 4through the recesses 16 and through the bights of the loops 15 to co-actwith such loops in looking one side of the top to the wall 4, as shownin Fig. 2. By first removing the pins 19, and then partly lifting thefront side of the top to clear the loops 15 from the inner walls of therecesses 16. the top may be readily detached from the wall 4. as will beunderstood and therea t1 or pushed rcarwardly fOIflthQ pin'posepresently described. q-hc ios guide straps l2 and the connecting straps14 form slidable connections between the top and the wall 3 to enablethe top to be moved over the box or be pushed rearwardly there fromuntil the loops 15 ot' the connecting straps H reach the oti-sets 13 ofthe guide strap 12, when such loops and the oft-sets of such guide strapwill enable the top to be turned as up n a hinge, to a position parallelwith the side all 3, as shown in Fig. 7. The ends of the top 4 are hereshown as provided with reinforce straps or plates 20 which are U-shapedin cross-section.

Each end wall 2 is provided 311 its vertical edges with recesses 21which extend from nearly the upper side thereof to nearly the lower sidethereof. In the shoulders 22-23 formed at the upper and lower ends ofsaid recesses arc vertical openings 24.- which are here shown as linedby lneans'of sheet metal tubes 2-5. The openings in the side wall 3,

in which the pins 19 are placed, are also shown as lined by sheet metaltubes 26.

Each side wall 3-4 is provided on its inner side at its ends withreinforcing plates 27 each of which is bent to form a doubled innerflange 28, a loop 29 to engage one of the recesses 21 of one of the endwalls 2 and an outer portion 30 to extend around the edge and to theouter side of said wall. The end portions of the said straps 27 areextended and bent over the upper and lower edges of the side walls, asat 31. When the box is set up aud the loops 29 of the straps 27 attachedto the side walls have been insorted in the recesses 21 of the end wallthey cause the flanges :28 of such straps or plates to bear against theinner side of such end walls. Pins 32 are inserted in the bights of suchloops and in the coincident openings Q-t at the upper and lower ends ofsuch recesses 21 to detachably secure the side walls to the end wallsand hence firmly, yet detachably. secure the corners of the box. hen thebox has been folded. as shown in Fig. 7, and disposed compactly, thesame may be secured by a wire 33 passed around the same longitudinallyand transversely and having its ends connected together, as at "he boxthus constructed is exceedingly strong and durable and may be readilyset 1p for use and folded compactly when empty for storage and shipment,and when folded may be shipped from one point to another at slightexpense owing to the compact. disposition of the parts thereof whichenables a number of boxes to be placed in a comparatively small space.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent is':

1. A folding box comprising a bottom, end walls hinged thereto forfolding on the same and provided with recesses in their side edges, sidewalls provided on their inner sides at their ends with plates, suchplates provided with inwardly extending flanges to bear against theinner sides of the end walls and with similar flanges to enterthe saidrecessesin the side edges of said end walls, a top connected. andfoldable on one of the side walls and hinges connecting said side wallsto the bottom, the said hinges of the respective side walls havingextended leaves of unequal length adapting one-of said side walls tofold on the end walls and the other side wall to which the top is con-'nected to told on the first mentioned side wall, substantially asdescribed.

'2. A box having converging walls, one provided with a recess in oneedge and the other having a plate 011 its inner side opposed to saidedge, said plate having a doubled portion forming a flange to enter suchrecess, a doubled portion forming a flange to bear against the innersurface of the recessed wall and further provided with an extendedportion bearing on the end of the wall to which such plate is attachedand a further extended portion bearing against the outer side of suchwall at said end.

3. A box having converging walls, one provided with a recess in one edgeand the other hating a plate on its inner side opposed tosaid edge, saidplate-having a doubled portion 'l'orn'ling a flange to enter such recessand a doubled portion forming a flange to bear against: the innersurface of the recessed wall.

In test imony whereof, I a'fiix my signature in presence of twowitnesses.
